CircTTBK2 level was increased in glioma tissues and cells. (A) The expression level of circTTBK2 in glioma tissues and normal tissues was detected through qRT-PCR assay. (B) Fold change of circTTBK2 expression level was presented as log2 (tumor/normal). (C) The overall survival of glioma patients with high/low circTTBK2 expression level was analyzed by Kaplan-Meier survival analysis. (D) The expression level of circTTBK2 in T98G, LN229 and NHA cells was determined by qRT-PCR assay. (E) After T98G cells were treated with Act D at indicated time points, the abundance of circTTBK2 and TTBK2 was examined via qRT-PCR assay. (F) The expression levels of circTTBK2 and TTBK2 mRNA in T98G cells treated with or without RNase R were examined by qRT-PCR assay. *P<0.05.
